Think about it like if when you signed up for stack exchange they just assigned you a random number rather than letting you pick a name.Īs to why you didn't have to reverify your account via SMS, if the iOS backup also backed up the app's data and configuration then the app would have everything it needs to connect as your account.
#WHATSAPP LOGIN ID INSTALL#
Also note that when you install the app you're effectively just creating an account where your username happens to be your phone number.
The key is to notice that in all of this the App doesn't actually use telephony services, so it can't use your phone number in the traditional manner. Then the server repeatedly requests the receiver acknowledge receipt of the message. When a user sends a message, it first travels to the WhatsApp server where it is stored. WhatsApp follows a ‘store and forward’ mechanism for exchanging messages between two users.

Upon installation, it creates a user account using one's phone number as the usernameĪ 2012 update now generates a random password on the server side. The second method seems smart since no one knows the SMS code except you, but this isn't secure either, because government or anyone who has a connection, for example, would have no problem getting all incoming SMS message for any phone and from there they can reverse engineer WhatsApp app and embed that as well. The first method is stupid if it's true, because any smart guy can reverse engineering and modify WhatsApp code and embed any phone number he want to hack.
#WHATSAPP LOGIN ID VERIFICATION#
WhatsApp embeds the verification code you get via SMS into the app itself and uses that as identifier to that phone number.WhatsApp embeds your phone number during verification process into the app itself.So that's telling me WhatsApp does one of two things: I backed up my iOS App from my old deviceĪnd it works without any need for SMS verification for new device.Of course, the app still has some other security problems to address….How does WhatsApp identify a specific user in order to forward the messages to him?
#WHATSAPP LOGIN ID ANDROID#
The update is rolling out to Android and iOS devices “over the coming weeks.” It’s a small but welcome update if WhatsApp needs you to have your phone in hand to scan a QR code in the first place, it might as well make sure it’s the right person making the connection. It’s better to just prevent this from happening in the first place. You can currently check which desktop devices are currently linked to your phone by going to the mobile app, hitting the menu button, and selecting “WhatsAppWeb.” But having that feature tucked away under a menu means you’re unlikely to notice an unauthorized login unless you’re specifically looking for it. Presumably, you’ll be asked to enter a pin or other security code we’ve asked WhatsApp for clarification.
WhatsApp is using your device’s system authentication for this - no need to register a new fingerprint - but it’s not clear what happens if you aren’t using biometric authentication. The update naturally prevents this scenario from happening, much like how app stores and banking apps require biometric authentication before making a purchase.
